Txhawm rau txhim kho kev xaiv cov txheej txheem (txhim kho cov txiaj ntsig thiab cov neeg sawv cev ua npuas dej uas muaj txiaj ntsig zoo ntawm cov roj hmab, cov tswj hwm feem ntau siv hauv cov txheej txheem frotation. Cov kev kho hauv cov txheej txheem frotation suav nrog ntau cov tshuaj lom neeg. Raws li lawv lub luag haujlwm hauv cov txheej txheem frolotation, lawv tuaj yeem faib ua cov txheej txheem, cov neeg sawv cev, cov neeg sawv cev hauv nruab nrab, cov neeg sawv cev hauv nruab nrab uas tuaj yeem tiv thaiv lossis txo cov adsorption lossis kev ua tiav ntawm cov Tus sau rau saum npoo ntawm tsis-flotation minerals, thiab tsim hydrophilic zaj duab xis nyob rau saum npoo ntawm cov merals. Sodium oxide inhibitor yog ib qho tseem ceeb inhibitors hauv cov txheej txheem frolotation.
Yuav ua li cas sodium oxide inhomitors ua haujlwm
Lub hauv paus ntsiab lus tom qab siv cov sodium oxide (NA2O) ua tus neeg nyob hauv cov ntxhia pob zeb cuam tshuam nrog nws cov tshuaj lom neeg thiab kev sib cuam tshuam nrog cov ntxhires chaw. Kab lus no yuav qhia tau meej cov qauv molecular, cov mis mos, tshuaj lom neeg thiab Inhibition tshuab. Molecular qauv thiab tshuaj cov tshuaj cov tshuaj noj kua txiv ntawm cov kua dej huv si ntawm cov pa dej ions (na ^ +) thiab cov pa oxygen (O ^ 2-). Hauv cov ntxhia freatation, lub ntsiab muaj nuj nqi ntawm sodium oxide yog ua kom muaj cov pa ntawm cov ntxhia thiab inhibiting lub flotation ntawm qee cov minerals. Daim ntawv thov thiab cov ntsiab cai ntawm sodium oxide hauv cov ntxhia flotation
1. Nto deg oxidation kev tawm tsam thaum cov txheej txheem pob zeb hauv av, sodium oxide tuaj yeem yauv tawm cov tshuaj tiv thaiv oxidation nrog cov nplaim taws me me. Qhov kev tawm tsam no feem ntau yog cuam tshuam nrog cov sodium oxide reacting nrog cov ntxhia lossis ua kom muaj cov txheej txheem sib txawv ntawm cov ntxhia ntawm cov ntxhia. Piv txwv, rau cov pob zeb ntxhia muag (xws li fe2o3 lossis FeS-om) 3) 2NaWeo2 + Cov kev tawm tsam no ntawm 3h2o ua rau muaj cov hlau hlau hlau kom tau them nrog cov daus hlau Oxide, yog li txo nws cov adsorption muaj peev xwm nrog cov neeg sawv cev flotation (xws li cov neeg sau ntawv), txo nws txoj kev ua tau zoo, thiab ua tiav qhov kev sib luag ntawm cov ntxhia. 2. Phooj ntxiv qhov sib ntxiv ntawm cov sodium oxide tuaj yeem hloov kho tus nqi PHIC ntawm lub cev flotation. Muaj qee kis, hloov cov ph hniav daws yuav cuam tshuam rau cov yam ntxwv them nqi thiab tshuaj ntawm cov ntxhia, yog li cuam tshuam cov ntxhia xaiv thaum lub sij hawm flotation. Piv txwv li, hauv frolotation ntawm tooj liab cov zaub mov, tsim nyog p Phaj Phaj yog qhov tseem ceeb heev yuav inhibit cov flotation ntawm lwm cov neeg los ntawm lwm cov neeg uas tsis huv. 3. Xaiv cov zaub mov tshwj xeeb ntawm cov zaub mov tsis muaj txiaj ntsig ntawm Sodium oxide feem ntau muaj ib co degree ntawm kev xaiv thiab tuaj yeem ua tiav qhov nyhuv inhibitions ntawm cov zaub mov tshwj xeeb. Piv txwv li, qhov kev cuam tshuam cov mineral hlau yog qhov zoo dua vim tias cov tshuaj tiv thaiv hlau oxide yog qhov muaj zog tau ua tau zoo nrog tus neeg sawv cev flotation. 4. Cov yam cuam tshuam rau qhov cuam tshuam ntawm cov socium oxide thiab cov qauv tshuaj lom neeg, suav nrog cov khoom siv tshuaj ntsuab, suav nrog cov khoom siv hauv cov ntxhia, tus nqi ntawm tus nqi ntawm cov tshuaj, thiab lwm yam kev ua haujlwm hauv cov txheej txheem flotation. Cov kev ua haujlwm no ua haujlwm ua ke los txiav txim siab lub inisitia cov nyhuv thiab haumab muaj peev xwm ntawm sodium oxide hauv qhov chaw ua kom sov. Cov ntsiab lus thiab kev thov kev xam pom ua tus neeg nyob hauv cov ntxhia ntxaij kom hloov nws cov khoom hauv av, yog li ua tiav kev xaiv tsis pub cuam tshuam ntawm cov zaub mov tshwj xeeb. Nws cov tshuab kev nqis tes cuam tshuam nrog kev hloov pauv oxidation sib txawv, pH hloov kho thiab cuam tshuam rau cov ntxhia cov khoom siv. Nrog rau kev tshawb nrhiav hauv qhov tob tob tob tob ntawm cov ntxaij flotation kev tshawb xav thiab thev naus laus zis, muab cov kev ua haujlwm thiab cov kev daws teeb meem ntau ntxiv. Qhov kev sib xyaw ua ke ntawm kev tshawb xav thiab kev coj ua muab cov ntxhia flotation flotation engilitors kom ua rau muaj kev ua kom zoo dua cov ntxhia rov qab thiab cov khoom lag luam zoo.
Daim ntawv thov ntawm sodium oxide inhibitors
Thaum tham txog cov khoom thov ntawm sodium oxide raws li cov ntxhia flotation inhibitor, nws tuaj yeem pom tias nws ua lub luag haujlwm tseem ceeb hauv kev sib txawv. Hauv qab no yog ntau cov ntaub ntawv thov tshwj xeeb: 1. Daim ntawv thov hauv ore femals, xws li hlau oxides (xws li hlau cav) thiab hlau-muaj cov sulfides. Cov khoom (xws li pyrite). Nyob rau hauv cov txheej txheem flotation ntawm hlau ore, thaum nws yog qhov tsim nyog los txhim kho cov hlau tsis zoo, sodium oxide tuaj yeem siv los ua tus inhibitor kom inhibit lub flotation ntawm hlau minerals. Piv txwv li, thaum ua tus xov tooj tooj liab uas muaj cov hlau sulfides, sodium oxide tuaj yeem ua rau cov hlau ruaj khov, yog li inhibiting cov flotation ntawm cov tooj liab thiab tso cai ntawm tooj liab. tus nqi tau zoo dua. 2. Kev thov nyob rau hauv flotation ntawm tooj liab-zinc ore ntawm tus txheej txheem tooj liab-zinc ore, nws yog feem ntau cia siab los txhim kho cov neeg xaiv rov qab thaum lub sijhawm flotation ntawm zinc. Hauv qhov no, sodium oxide tuaj yeem ua kom zoo dua rau cov kev daws teeb meem, yog li ntawd hauv cov tshuaj flotation, yog li nce rov qab tus nqi tooj liab thiab qib. 3. Daim ntawv thov nyob rau hauv flotation ntawm txhuas-zinc sulfide ore yog feem ntau nrog cov tshuaj hlau, thiab muaj cov tshuaj tua hlau, thiab muaj cov tshuaj tua kab hlau yuav cuam tshuam cov flotation nyhuv ntawm txhuas thiab zinc. Hauv kev kho cov hmoov txhuas-zinc sulfide ore, ua kom cov flotation nrog cov roj av ntawm cov txhuas rov qab los ntawm cov txhuas thiab zinc Cov. 4. Daim ntawv thov ntawm phosphote minerals hauv flotation phosphate cov zaub mov (xws li hauv phosphorus, thiab lwm yam.) Flotation muaj kev cuam tshuam. Sodium oxide tuaj yeem siv los ua tus neeg nyob hauv qhov xwm txheej no, yog kom muaj kev sib cuam tshuam nrog cov tshuaj footor lossis foaming, yog li nce siab ntawm lwm cov khoom muaj txiaj ntsig (xws li Tooj liab, npib tsib xee, thiab lwm yam) Tig xaiv thiab rov ua haujlwm tus nqi. 5. Daim ntawv thov ntawm silicate zaub mov hauv frotation silicate zaub mov (xws li quartall cov zaub mov (xws li tooj liab, zinc, txhuas , thiab lwm yam) cov nyhuv flotation. Sodium oxide tuaj yeem txo cov kev sib tw ntawm cov pa roj thav duab los ntawm kev kho tus lej pH, yog li ua kom rov zoo dua tus nqi thiab qib ntawm nws yog xim hlau.
